Blade Installation
Procedure
Tools Required:
Hex Keys: 1/16", 7/64"
Parts May Be Required:
Blade: K83987
Cap Screw: M54587
Set Screw: A02887
Special Instructions:
It is critical the knife and blade be assembled with a zero-gap to ensure
clean cut-off. Once correctly positioned, use threadlocking compound
to prevent parts from shifting during use (allow sufficient time for
compound to cure).
Installation Procedure:
Set the tool tension to -0-.
1.
Back-out cap screw (M54587) and set screw
2.
(A02887) - Figure 1.
Reposition/replace blade, but do not fully tighten
3.
screws yet.
Squeeze the handle completely and firmly strike the
4.
pull up lever against a non-metal surface to actuate
the knife - Figure 2 (note: you may also press firmly on
the pull up lever to actuate the knife - Figure 3).

Blade Installation
Procedure
Installation Procedure Continued:
Open the tension handle slightly so that the
6.
knife retracts from its full stroke; it should be
overlapping the blade edge - Figure 5.
Using the edge of a table or bench, force the
7.
pull up lever against the blade. This will force
the blade against the knife and ensure a zerogap - Figure 6.
Tighten the cap screw 1/2 turn past snug.
